Objective

This program focuses on finding out more information on Asian Shore Crabs. Scientists need more research about this species. By finding the ration between native and non-native data analysis overtime, we can answer such questions as:• Are these species endangering the native species?• Are the crabs eating what’s under the rock and taking over?• Or, are they eating enough to co-exist with the native crabs?

Are Asian Shore Crabs a threat or an addition to the native species of NY Harbor?

Background

Are Asian Shore Crabs Marine Invaders... or Marine Immigrants? Your students can help scientists figure this out by following scientific protocols and collecting data.

Asian Shore Crabs first appeared in U.S. waters around 1988, probably arriving in ballast water from ships that had arrived from Asia. These crabs can be found along the east coast of the U.S. from Massachusetts to North Carolina. Their numbers seem to be increasing, along with their range of habitat.
